向量是高中数学的一个重点内容,在研究几何和代数问题时经常会用到向量。由于向量这方面内容在高中数学课程中有所增加,因此,也要用新思路解决相关的问题,本文分析了向量法在平面几何、立体几何、不等式和三角函数中的运用,希望通过对向量 Vector is a high school mathematics a key content, often in the study of geometry and algebra problems vector. Because of the increase of vectors in high school mathematics curriculum, we must also solve the related problems with new ideas.This paper analyzes the application of vector method in plane geometry, solid geometry, inequality and trigonometry,
